How do you create a UIImageView programmatically in swift

UIImageView class provides a view container for displaying either a single image or for animating a series of images. In this example we are going to display an image inside a frame that is smaller in size. With the help of ContentMode UIViewContentModeScaleAspectFit we can scale the content to fit the size of the view by maintaining the aspect ratio. Please see the reference Guide for other content modes that may help you set the image respective to the view frame. In this tutorial we are going to learn the following
  • Display an image on the screen
  • How to resize the image to fit the view frame
  • Animate a series of images

var imageViewObject :UIImageView
imageViewObject = UIImageView(frame:CGRectMake(0, 0, 100, 100));
imageViewObject.image = UIImage(named:"imageName.png")

  • How to resize the image to fit the view frame
imageViewObject.contentMode = UIViewContentMode.ScaleToFill
imageViewObject.contentMode = UIViewContentMode.ScaleAspectFit
imageViewObject.contentMode = UIViewContentMode.ScaleAspectFill

  • Animate a series of images
                         delay: 2.0,
                         options: .CurveEaseInOut | .AllowUserInteraction,
                 animations: {
                      self. = CGPoint(x: 75, y: 200)
                 completion: { finished in
                       println("Bug moved left!")
